(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A box of massm_{1}is hanging from a cable of negligible mass, The cable rounds a pulley, where it is connected to a second box of massm_{2}on a frictionless plane. The angle of the inclined plane is [tex]\theta[/tex] as measured from the flat ground. Both boxes are initially at rest. Find the acceleration of the boxes and the tension in the cable.

2. Relevant equations

[tex]\overline{F}[/tex]=m[tex]\overline{a}[/tex]

[tex]\overline{n}[/tex]+[tex]\overline{F}[/tex]_{g}=m[tex]\overline{a}[/tex]

3. The attempt at a solution

Object A had massm_{1}and object B has massm_{2}.

I know that gravity and the cable tension are both affecting object A, and the cable tension, gravity, and a normal force from the plane are affecting object B. Therefore, I have:

Object A: T_{A}+ F_{gA}= m_{1}a

Object B: T_{B}+F_{gB}+ n = m_{2}a

(where T, F, and a are all vectors)

I tried drawing free-body diagrams, and I just get lost drawing all of the equations...I know I need to make component vectors, but there is a lot to the problem, and I'm feeling a little overwhelmed.

Is this stuff correct so far? Thanks.
